example 1
[0039] Take by weighing 2000 grams of aluminum hydroxide powder (dried rubber powder produced by Changling Branch Catalyst Factory, dry basis 72% by weight), extrude into a butterfly bar with a circumscribed circle diameter of 1.3 mm with an extruder, and wet the bar at 120 ° C Drying for 4 hours and calcining at 600° C. for 3 hours to obtain carrier S1.
[0040] Take by weighing 50 grams of ammonium molybdate (Tianjin, analytically pure) and join in 120 milliliters of water, add dropwise the ammoniacal liquor that concentration is 25% to ammonium molybdate and dissolve under heating and stirring, then add 30 grams of cobalt nitrate (Beijing, analytically pure), stir After dissolving, add 20 milliliters of ethanol (Beijing, analytically pure), add water to 200 milliliters, impregnate 100 grams of carrier S1 in excess, and place the system in a synthesis reactor for reaction for 4 hours. The reaction conditions include: temperature 150 ° C, pressure 0.7MPa, where, P 0 =0.5MPa,...
example 2
[0042] Weigh 15 grams of basic cobalt carbonate (Jiangxi, analytically pure) and 30 grams of molybdenum trioxide (Tianjin, analytically pure) and add them to 120 milliliters of water, add 10 grams of phosphoric acid (Beijing, analytically pure) under stirring, heat and stir to dissolve, add 15 milliliters of isopropanol (Tianjin, analytically pure), add water to 200 milliliters, excessively impregnate 100 grams of carrier S1, and place the system in a synthesis reactor for 10 hours of reaction. The reaction conditions include: temperature 200 ° C, pressure 2.1 MPa , where P 0 =1.5MPa, ΔP=0.6MPa, after cooling and filtering, the obtained sample was dried at 120°C for 2 hours and calcined at 250°C for 3 hours to obtain catalyst B-2. The composition of catalyst B-2 is shown in Table 1.
example 3
[0044] Take by weighing basic nickel carbonate (Shensheng, analytical pure) 20 grams and join in 150 milliliters of water, add 8 grams of phosphoric acid (Beijing, analytical pure) under stirring, heat and stir to dissolve, add ammonium molybdate (Tianjin, analytical pure) respectively under stirring ) 12 grams, ammonium metatungstate (Sichuan, analytically pure) 110 grams, add water to 200 milliliters, excessively impregnate 100 grams of carrier S1, and place the system in a synthesis reactor for 24 hours of reaction. The reaction conditions include: temperature 100 ° C , introducing nitrogen to make the reaction pressure 5.2MPa, where, P 0 =0.2MPa, ΔP=5.0MPa, after cooling and filtering, the obtained sample was dried at 120°C for 2 hours and calcined at 200°C for 3 hours to obtain catalyst B-3. The composition of catalyst B-3 is shown in Table 1.
